Specification of Letters Patent.

Patented Aug. 23, 1921.

Application filed November 20, 1919. Serial No. 339,361.

full, clear, and exact description of the invention as will enable others skilled in the art to practice the same.

The invention relates to internal combustion engines and more particularly to means 7 for heating the intake manifolds of those used on automobiles.

The object of the invention is to provide a means for quickly vaporizing the gasolene as it passes through the intake manifold to the cylinders of the engine in cold weather. It is well known that it is difiicult to start automobile engines in cold weather unless they are kept in warm places, because of the difliculty in vaporizing the fuel so that it will ignite.

Briefly the invention comprises a tray adapted to be secured to or about the intake manifold in a position such that flames from liquid fuel ignited in the tray will come in contact with the manifold and heat the same, whereby gasolene drawn therethrough from the carbureter will be heated sufliciently to properly vaporize for explosion when it reaches the cylinders.

In the drawings forming a part of this specification,

Figure 1 is a cross section of the devlce taken on line 1-1 of Fig. 3.

Fig. 2 is a cross section taken on line 22 of Fig. 4.

Fig. 3 is a plan view.

Fig. 4 is an elevation showing the devlce in use.

The drawings show the upright portion 8 of an intake manifold leading from a carbureter (not shown) and having the d1- verging arms 10 leading to the cylinders. The heater comprises a tray havlng s1de walls12 and a bottom 14. The tray has a middle portion 16 which lies in front of the manifold part 8 when in operative posltion as shown in Fig. 4, and two enlarged end portions 18 which extend beyond the mamfold portion 8 and are positioned largely beneath the arms 10 of the manifold.

A neck 20 rises from the rear wall of the middle part 16 'of the tray and curves up over the top of the manifold in the form of a hook as shown, and in the top of this a vertically disposed set screw is placed as at 24, this screw being adapted to bear against the manifold to bind the heater in place. The inner side walls of theoenlarged tray portions 18 are provided with engaging faces 26 adapted to bear upon and be drawn up tightly against the under side of the manifold when the set screw 24 is tightened. Thus the heater is firmly held.

To use the heater it is merely necessary to pour into the tray a small quantity of gasolene, alcohol or the like, and touch a match to the same. This fuel will soon burn off leaving the manifold hot enough to vaporize the gasolene drawn through the carburetor sufficiently for explosion. I

In order to obtain more eflicient combustion of the fuel in the tray, a plurality of upstanding studs 30 are formed on the bottom of the tray and these are drilled at 32. The passages 32 supply an increased amount of air to flames, thereby securing better combustion and more heat.

I claim: 7

1.. In emnhination, a T-shaped intake manifold, and a heater therefor having .11"'Z1111Ql11iJQlS for fuel underlying the t1 ns'verse portions of the manifold, said nie1.,.iers having means on their upper edges engaging the under sides of said transverse portions, and hooked means overhanging and engaging the top of said manifold whereby the heater is secured thereto.

2. A heater for a T-shapcd intake manifold comprising a fuel tray adapted to be positioned adjacent a lower portion of the manifold and hook-shaped member to overhang and engage the top of the manifold for securing the tray to the manifold.

A. heater for a T-shaped intake manifold comprising a fuel tray having a portion adapted to be positioned beneath a transverse portion of the manifold and having an upper edge to engage the under side of said transverse portion, and means to overhang and engage the top of the manifold for securing the tray to the manifold.

4. A heater for a T-shaped intake manifold comprising an open tray for fuel, the tray having a port-ion adapted to lie in front of the vertical portion of the manifold and end portions ada'ted to lie beneath the transverse parts 0 the manifold for heating tion.

6. A heater for a T-shaped intake manifold comprising an open fuel tray having a middle portion adapted to lie in front of a portion of the manifold and end portions adaptedto lie at the sides of the manifold portion and. beneath transverse portions of the manifold, said tray having upper edges adapted to engage the under sides of said transverse portions, and a hook on the tray adapted to engage the top of the manifold.

7. A heater for an intake manifold comprising a fuel tray having a portion adapted to lie beneath a portion of the manifold, the

bottom of the tray having an aperture therethrough for supplying air to fuel in the tray remote from the edges of the tray, and means for positioning the tray in operative relation. 1

8. YA heater for an intake manifold comprising a fuel tray having portions adapted to lie beneath a portion of the manifold,

formed in said studs for supplying air tofuel in the tray remote from the edges thereof, and hook-shaped member for mounting the tray on the manifold.

9. A heater for an intake manifold comprising a fuel tray having a portion adapted to lie beneath a portion of the manifold, studs mounted on the bottom of the tray and extending vertically therein, said studs having apertures formed vertically therethrough to supply air to the tray, and means for mounting the tray on the manifold.

10. A manifold heater comprising a tray open at the top and adapted to contain a liquid fuel, and means on the tray to support the same from the manifold and beneath an arm thereof in order to heat the arm.

11. In combination, an intake manifold for internal combustion engines having a transverse arm, an open tray adapted to contain a liquid fuel, said tray being positioned beneath said arm whereby the exterior of the arm may be heated from flames rising from the tray, and means on the tray for supporting the same from said manifold and in said position. v

In testimony whereof I ailix my signature.
